Advances in the Cyanidation of Gold - Gold Ore Processing (Second .

May 13, 2016 . Abstract. Cyanidation, a process used for over a century to extract gold from free milling ores, is so effective that it can economically treat low-grade ores (0.5 g/t Au). The concentration of cyanide added to dissolve gold is much higher than the stoichiometric requirement because of various interferences.

Gold cyanidation - Wikipedia

Gold cyanidation is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents.

Characterization of refractory behaviour of complex gold/silver ore .

A suitable pretreatment process is often required to overcome the refractoriness and render the gold accessible to the lixiviant action of cyanide and oxygen. [4]. Roasting, pressure oxidation, biooxidation, ultrafine grinding and modified cyanidation are the pretreatment methods currently practiced for refractory gold ores and.
